Abstract
This experiment was conducted to study the effect of two types of Probiotic products, imported and local products, on the performance characteristics of broiler chicks. A total of 500 broiler chicks, Hubbard at one day old, were randomly allocated in to three treatment groups. Chicks in each treatment group were subdivided in to five replicate with 50 chicks for each replicate. Chicks in the first treatment received control diet in the second treatment received locally Probiotic through feed at the level of 5 kg per ton feed while chicks in the third treatment received imported Probiotic through drinking water, Statistical analysis showed that exceed single Probiotic and multiple Probiotic on control group in body weight at 4, 8 week. Where as have not any significant reietonship between single Probiotic and multiple Pribiotic in body weight at 4, 8 week. Multiple Probiotic exceeded on single Probiotic and control group in feed in take at 4 week. But there was no significant between three treatments at 8 week in fed in take. Also result show significant single Probiotic in feed efficiency at 4 week on multiple Probiotic and control group and the resulted show single Probiotic and multiple Probiotic surpaso control grop al thay have not any significan differant between them on control group at feed efficiency at 8 week .Further more result reveal significant effect on the single Probiotic and multiple Probiotic have surpassed on control group in mortality rate within age 8 week. It was noticed from result significant single Probiotic and multiple Probitic on control group in dressing percent at 8 week , where as no significant different is seen between single Probiotic and multiple Probiotic in this respet at 8th week . Using single Probiotic and multiple Probiotic led to increasen production Index Value and the Economic index in comparison with control group at 8th week
